WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 658,484, dated September 25, 1900.

l Application filed April 24, 1900. Serial No. 14,160. (No model.)

To rtZZ whom it may concern:

Be it known that I, CHARLES W. FRANZ- HEIM, a citizen of the United States, residing at Wheeling, in the county of Ohio and State of \Vest Virginia, have invented a new and useful \Vater-Closet, of which the following is a specification.

This invention relates to water-closets of that type in which a siphon or other discharge is employed to the soil-pipe and a flushing orgravity valve is used at or near the Water-inlet. v

The object of the invention is to provide a construction in which the usual overhead tank will be dispensed with, the flushing being secured by siphonic action, which is inaugurated by air-pressure instead of by gravity, as is usual, the air-pressure being obtained by utilizing the pressure in the service-main.

In the drawings forming a portion of this specification, and in which like numerals .of reference indicate similar parts in the several views, Figure 1 is a plan view of a closet embodying the present invention. Fig. 2 is a vertical central section of the closet. Fig. 3 is a rear elevation of the closet.

Referring now to the drawings, the closet comprises a base 10, the hopper or bowl 11,

and a siphon, including a long log 12 and a short leg 13, the long leg being returned under the bowl and then continued downwardly and terminating in a soil pipe nipple 14.

These portions of the closet are Well known to those skilled in the art and require nofurther specific description.

The leading feature of the present invention consists in making a combined air and Water reservoir as an integral part of the structure that includes the bowl, its base, and the siphon, and in the drawings herewith I have shown the reservoir as surrounding the bowl, portions of the siphon being extended exteriorly thereof. In the formation of this reservoir a shell or wall 15 is pro;

vided around the bowl equal in depth to the closet and joined firmly to the base lOand the rim of thebowl, so as to 'produce water and air tight joints in the practical structure of the closet. The shell is somewhat reen- The flushing-rim 17,

which projects inwardly from the upper edge of the bowl, is formed integral with or is se cured to the bowl, as may be preferred.

It will be noted upon reference to Fig. 2 of the drawings that the short wall of the bowl, beneath which the short leg of the siphon opens, extends downwardly to a point below the top of the siphon, so that when the bowl is filled to a point above the lower end of this short wall a water seal is formed in the usual manner.

Communicating with the uppermost point of the circular wall of the bowl are the usual flushing-openings, through which the water is contributed to the bowl, and leading to these openings is a flush-pipe 18, with which communicates a pipe 22, leading from a point .23 at the base of the reservoir, the communication between the pipes 22- and 18 being through a valve having an operating-lever 25, through the medium of which it may be opened and closed, the closure being directly eifected by means of the usual closing-spring arrangement. I

A water supply or feed pipe 20 leads from the water-main to the reservoir, at a suitable point thereof, and has a regulating-cock 21,

through the medium of which the flow ofwater may be regulated. This feed-pipe stands normally open, and hence with the parts constructed as above described the water will flow into the reservoir until the air thereinis compressed toa point to balance the pressure in the feed-pipe. At this time the valve 24 is closed, and if such valve be then opened the expansive force of the compressed air in the reservoir will force the Water from the bottom of the reservoir upwardly through pipe 22, valve 24, and pipe 18 to the bowl, the cross-section of pipe 22 being such as to insure the passage of the water in a volume sufficient to start the siphon, or, if preferred, the usual jet connection may be made between the pipe 18 and the jet-open ing in'the bowl at the lower end of the short leg of the siphon. Furthermore, if preferred, the feed-pipe may be passed inwardly of pipe 22,s0 that during the operation of flushing the water therefrom will be discharged div rectly to the bowl and will assist the airpressure in forcing the water from. the reservoir to the bowl.

In the manufacture of .the closet I prefer to use porcelain, and when making of this material I first construct the bowl and rim, to-

gether with the siphon, as also the base. I'

afterward construct the shell 15, either in plain or ornamental design, and while the parts are 'yet in their plastic condition the shell is united at its edges to the base and bowl, after which the .entire device is fired, thus forming it integral.

If preferred, the parts may be formed of metal or other material or materials and assembled in the relation specified, after which it may be enameled to prevent corrosion. It will be understood, however, that I do not restrict myself to any specific material or combination of materials.

While I have shown the reservoir-chamber surrounding the bowl, it may of course be of any shape and only partly surround the bowl, or it may be located at one or two sides of the bowl, in front, behind, or above the bowl, as may be preferred. Furthermore, a pressureregulator may be applied to the pipe 20,whereby the pressure contributed to the reservoir may be only a fraction of that in the main, and air-chambers may be attached to the reservoir to act as cushions while under pressure.

What is claimed'is- 1. A Water-closet comprising an annular reservoir having an enlarged base and a contracted upper end, the walls of the reservoir between their ends being ren'trant, a downwardly-tapered bowl in the upper portion of the reservoir,and a siphon connected with the bowl, said siphon passing beneath the bowl and out through the bottom of the reservoir, said bowl extending from the upper edge of the reservoir to close the upper end of the latter and having its lower end sustained by the siphon, said reservoir,- bowl and siphon being formed integral.

2. A water-closet comprising a bowl, a reservoir completely surrounding the bowl and having its upper end closed by the bowl, a siphon connected with the bowl and passed outwardly beneath the bowl and through the bottom of the reservoir and sustaining the bowl, said reservoir, bowl and siphon being formed integral.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
